Thank-you for your reply and suggestions.
I rebooted into "safe mode with networking" and the Launcher started up as expected. I am not running any third party anti virus or anti malware software - just what comes with Windows 10.
What is my next step?
Your help is greatly appreciated. DxLabs is the hub for all my operating - from controlling my Flex 6400 to working FT8, logging. etc. The new laptop is what I plan to do all my operating on.
